Which monster do you like the most in Heroes 5 (level 6)?

I’ve found a new favorite! Imagine a tank with decent speed and initiative, with 27 attack/23 defense and 140 hit points, which is also 50% resistant to magic and simply crushes lower-level units (as it adds +2 damage to each attacked unit!). That’s amazing! This is the Cavern Horror – an alternate upgrade for the Cavern Lord!
